Apple keyboards on laptops and the mini external keyboards have fn shortcuts for the end key:

Other keyboards too: http://superuser.com/questions/412761/mini-keyboard-has-no-home-end-keys-how-to-type-them

So it would be Ctrl+Shift+Fn+Right for you. I know this because my keyboard in question is an Apple keyboard. I assume this is the keyboard you're referring to. Almost all keyboards have "End" in some form because it's far too common in applications to get away with omitting.

That said, maybe it's worth just having a configurable shortcut in mIRC's options window, that way we can just leave Ctrl+Break as the default and let users with different keyboards customize it in whatever way works for them.
